I have UBUNTU 16.04.05 LTS X64 and when I try to add any repositories I'm having the following error!
for example I have used:
sudo add-apt-repository ppa:noobslab/apps and the result is:
This PPA Contains Applications for Ubuntu/Linux Mint from different sources but debianized by http://www.NoobsLab.com More info: https://launchpad.net/~noobslab/+archive/ubuntu/apps Press [ENTER] to continue or ctrl-c to cancel adding it Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 168, in <module> if not sp.add_source_from_shortcut(shortcut, options.enable_source): File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 768, in add_source_from_shortcut self.set_modified_sourceslist() File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 492, in set_modified_sourceslist self.save_sourceslist() File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 658, in save_sourceslist self.sourceslist.save() File "/usr/lib/python3/dist-packages/aptsources/sourceslist.py", line 413, in save files[source.file] = open(source.file, "w") FileNotFoundError: [Errno 2] No such file or directory: '/etc/apt/sources.list.d/noobslab-ubuntu-apps-xenial.list' gpg: keyring `/tmp/tmph_0b92bg/secring.gpg' created gpg: keyring `/tmp/tmph_0b92bg/pubring.gpg' created gpg: requesting key F59EAE4D from hkp server keyserver.ubuntu.com gpg: /tmp/tmph_0b92bg/trustdb.gpg: trustdb created gpg: key F59EAE4D: public key "Launchpad PPA for NoobsLab" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) gpg: keyblock resource `/etc/apt/trusted.gpg.d/noobslab_ubuntu_apps.gpg': file open error gpg: no writable keyring found: eof gpg: error reading `/tmp/tmph_0b92bg/pubring.gpg': general error gpg: import from `/tmp/tmph_0b92bg/pubring.gpg' failed: general error
it always gives me this error with any sort of repositories that I try to add. I have tried many solutions I'm going to list them below:
and many many other solutions given to related problems. no one worked for me.
is there any solutions here?
file /etc/apt/sources.list is shown below:
